x + 3 + 2x = x + 9 x + 2x + 3 = x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 2x + 3 = 9 2x + 3 - 3 = 9 - 3 2x + 3 - 3 = 9 - 3 2x = 9 -3 2x = 6 2x/2 = 6/2 2x/2 = 6/2 x = 6/2 x = 3
1x plus 3x equals 4x. When you combine like terms, you simply add the coefficients of the variables together. In this case, 1 + 3 equals 4, so the final result is 4x.
The expression (2x \cdot 1x \cdot 3) can be simplified by multiplying the coefficients and the variables separately. First, multiply the coefficients: (2 \cdot 1 \cdot 3 = 6). Then, combine the variable terms: (x \cdot x = x^2). Therefore, the result is (6x^2).

To convert 3x to 1x, you can simply divide 3x by 3. This will give you 1x.
1x plus 4y produces a 3 dimensional cuboid when it is graphed.

If y=.1x+3, then .1x = y - 3. Multiply both sides by ten and x = 10y - 30.
The expression "negative x plus 3x" can be simplified by combining like terms. Negative x can be written as -1x, so the expression becomes -1x + 3x. When you combine -1x and 3x, you get 2x. Therefore, the simplified expression is 2x.
2x2+1x-3=0 4+x-3=0 x+1+0 x=-1 is your final answer
